Fix for old Ati cards under PCLinuxOS 2011 with the xorg 1.9.5

[aguila]

Installed the newest kernel and module i915 is being loaded at startup.

But driver i915 doesn't show up in PCC.

Am I doing something wrong? Should I install anything additional from Synaptic?

things went from bad to worse

tried to revert changes but system refused to go back to normal

i tried to edit xorg.conf file to delete the modifications and now system doesn't boot, not even on failsafe or level 3

system just hangs in starting named service

someone could please guide me to use the livecd to reconfigure the system?  i think that the problem is the xorg or the other two files

[T6]

ok, i remembered that i could press ctrl+alt+F1 and that allowed me to run XFdrake

still, i have this corruption

None of the changes that were made in the system would cause this.

I just removed the changes on my main machine and rebooted. All is good...

Maybe You need to re-add those options in the xorg.conf? You can also do this:

as root:

mv /etc/X11/xorg.conf.oldie /etc/X11/xorg.conf

to get Your old xorg from before the fix back...

Weird. Really weird...

before removing the extra lines in modprobe i couldn't take a picture, all the image was green

i'm thinking that maybe a good clean of the pc is necessary but yesterday i played in xp for 5 hours and no errors happened

i'm sure that the extra lines made other changes but no idea what to modify, since i culd reconfigure xorg, i could login gain

Mind boggles...

Site is working fine in my corner of the woods. Just to exclude problem with DNS I loaded it up from my mobile phone via gprs. It comes up fine.

Only three things need to be done to revert the entire process.

As root:

run:

mv /etc/X11/xorg.conf.oldie /etc/X11/xorg.conf

this will ask to overwrite the xorg.conf file. Press Y and then Enter. Now Your old xorg.conf is back.

Now edit /etc/modeprobe.preload and remove the last line with the word radeon in it. Radeon will no longer be modprobed at the system start.

Now edit /etc/modprobe.conf and remove the last line with the options radeon modeset=1 in it. Radeon modeset will be set to 0 upon reboot.

All changes reverted. Nothing else was done to Your system. And most definitely - the changes in my howto do not affect / overwrite anything else in Your system.

I just reverted all 3 of my machines. No problems beside the lack of the 3D acceleration.

I repeated the steps. Acceleration is back. No problems found.

"run:

mv /etc/X11/xorg.conf.oldie /etc/X11/xorg.conf"

that line won't help because i already generated a new xorg, the old one doesn't exist anymore, it was replaced by the non working copy

"Now edit /etc/modeprobe.preload and remove the last line with the word radeon in it. Radeon will no longer be modprobed at the system start.

Now edit /etc/modprobe.conf and remove the last line with the options radeon modeset=1 in it. Radeon modeset will be set to 0 upon reboot."

i already did that, the problem happened when i deleted the extra lines in the xorg.conf, i didn't deleted all of them because i already had some of those in use, that created the problem

i was comparing the old and the new xorg files, the old had the section device before the the section monitor

not sure what that means, the rest is practically the same to me

the image corruption persists after many reboots and many changes

i'm going to try a new user to see if i can replicate but form livecd no errors occurred

Maybe you can copy the xorg.conf file from a live session to your HDD and then replace the non-functioning one. If you're lucky you might even be able to copy the two modprobe files.

i tried to do that this morning but i discovered that i couldn't access to my / partition  

the modprobe is back to original state so i don't understand the problem

i just tried to enter in runlevel 3 and system failed to load identically, i had to call another tty and delete and recreate xorg

still same graphical corruption

just logged as root, the errors doesn't happen here

what is going on?!?

edit:

just reconfigured cursor, iconset, colors, plasma theme and all went magically to normal

that was fun but won't do it again

Thanks Andy,
  I decided not to wait any longer and followed your instructions. It took me a little searching and reading on how to edit a file but I have Wobbly Windows and The Cube back. Interesting thing, the 3d cube would usually freeze up within a minute before but it's smooth and doesn't seem to have any problems now.

Thanks again.

Cool beans . Glad it's working for You.

Just setup test-PCLinuxOS-KDE4-2011.6 on an older Athlon 2500 with ATI-9600

Only setup problems with the ATI

modified:
/etc/modprobe.preload, added radeon
etc/modprobe.conf, added options radeon modeset=1

now the right driver is loaded as explained in the start of this topic, still no 3D

modified:
etc/X11/xorg.conf, added Load "dri" in Section "Module"
as in:
Section "Module"
    Load "v4l" # Video for Linux
    Load "dri"
EndSection

now I've got Desktop Effects (not all but...)

Succes with your experiments.

Interesting. I didn't added this and the 3D is working fine.

Thanks for sharing.

The same section in my xorg reads:


Section "Module"
    Load "dbe" # Double-Buffering Extension
    Load "v4l" # Video for Linux
    Load "extmod"
    Load "glx" # 3D layer
    Load "dri" # direct rendering
EndSection

...and...

Section "Device"
    Identifier "device1"
    VendorName "ATI Technologies Inc"
    BoardName "ATI Radeon HD 2000 and later (radeon/fglrx)"
    Driver "fglrx"
    Option "DPMS"
EndSection

Yes, I have a different ATI card, but the entries here are typical for what I've seen in other ATI installs.  If you are not loading glx, I'm not surprised that 3D doesn't work.
